DOOR-HANGER.

Specification of Letters Patent.

Patented Sept. 15, 1914..

To all whom it may concern:

Beit known that I, CHESTER E. KINARD, a citizen of the United States, residing at in the county of VDelta and State of Texas, have invented certain new and uselful Improvements in Door-Hangers; and I do declare the following to be a full, clear,

`and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

therefor.

which is constructed in such a manner asv to normally take the weight of the door oif the supporting rollers and the track.

A secondary object is to'construct the hanger in such a manner as to apply a braking action to the track simultaneously with throwing the supporting rollers out of play, thus preventing the door from unnecessarily shifting.

With the above objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure 1 is a side view of a portion of a car showing the door closed and the supporting rollers thrown out of action; Fig. 2 is a similar view with the door raised and the rollers in position to travel on the track; F ig. 8 is a detail transverse section on the line 3-3 of Fig. 1; and Fig. 4 is a detail perspective view of one of the levers on which the supporting rollers are journaled.

.In the embodiment illustrated, I have shown a portion of a freight car 1 having the usual door opening 2, sliding door 3, track 4, guides 5 for the lower end of said door, and stops 6 for preventing excessive movement of the latter in either direction.

The door 1 may be of any suitable construction and is of slightly less height than the distance between the upper face of the guides 5 and the lower face of the track 4t, this provision being made for a purpose to appear. Rigidly secured to the upper corners of the door 1 are upwardly extending arms 7 which extend a suitable distance above the track Il, and have their free ends This invention relates to improvements in,` car doors and more particularly to hangers face p of offset in such a manner as to bring them direcgly above the active face of said track as at 4Pivotally mounted upon the upper ends of the arms Z are inwardly extending levers 9 which are here shown as being formed of single strips of strap metal bent substantially upon themselves and having their central portions turned outwardly as at 10 for the reception of supporting rollers 11 which `are journaled therein and are adapted to travel on the track 4.

y Depending from the outer side of each lever 9 is an arm 12 which has its lower end turned inwardly beneath The primary object of the same is to pro,- `vide a hangerV of the character described the track t to provide friction shoes 13 which are adapted to contactl with the lower said track in a manner to be described. The inner ends of the levers 9 are pivoted to offset terminals 14- or links 15, which are pivoted at 16 to the upper end of a connecting rod 17. The connecting rod 17 is slidably mounted through a guide 18 on the door 8 and is provided, on its lower end, with a ring 19 in which an eccentric 2O operates for raising or lowering the inner ends of the levers 9. The eccentric 20 may be provided with any suitable operating handle 2l for obvious reasons.

The operation of the device is as follows: Assuming that the door is open and supported upon the rollers 11, and it is desired to retain the same in this open position, the handle 21 of the eccentric 2O may be turned to such a position as to move the inner ends of the levers 9 upwardly. This action will allow the door 3 to lower and rest upon the guides 5 and will also cause the rollers 1l to rise out of contact with the track l and will bring the friction shoes 13 into binding contact with the underside of said track. It will be evident that the above operations will clamp the door 3 securely between the guide 5 on which it rests and the underside of the track 4L and will prevent any shifting thereof.

l/Vhcn it is desired to again close the door',

the eccentric may be turned in the proper direction for bringing the rollers 11 into Contact with the track and for rocking the levers 9 around the roller journals, and thus raising said door out of contact with the guide 5. The door may then be closed and closed position by means of any locked in suitable locking mechanism L. The door car thereto,

may be left in this'position, butis preterably again lowered until it rests upon Athe guides 5, thereby relieving thel track fi of the weight oi said door. 'l Y v Should the door be left partially open and supported upon the track l and rollers ll, it would remain in this position as long vand supporting rollers adaptedrto travel fas no suddenjarwere imparted to the'car. if, however, the car should be violently shaken by the process of coupling another the jar of said' operation will cause the eccentric 20 to turn around itspivot 22 and will thus allow the door todrop into contact with certain of the guides 5.

IcOnSiClerV the provision of the friction shoes 13 an extremely important feature of my invention, since by their action, the door may belocked in any desired position. y The Vspeciic structure of said shoes also prevents the rollers l1v from jiimping the Vtrack 4 when said rollers are raised or lowered, as the case may be.

I have describedmy invention with considerable minuteness, but I do not wish to;

Copies of this patent may be obtained Ifor vend to said door and carrying Y:be limitedstlo details-of construction, Y other thanthose amplified in the appended claim.

Having thus described, my f invention, whatlclaiin as new and desire to secureV by Letters Patent is: Y

vThe combination with a sliding door,

` guides orthe lower end thereof, a track,

thereon, ofleversipivotally connected at one the journals for said rollers intermediate their ends, links necting rod pivotedrto said links, a ringon Asaid connecting rod and an eccentric-jourvnaled on said door andop said ring lfor raising or loweringsaid lever for the purposefset forth. Y

In testimonywhereot I have hereunto set eratingwithin pivotedj to the tree ends of said levers, a 'conp iny hand in presence ,of two subscribing witnesses. A Y v CHESTER E. KINARD.
